Java/Language Basics/Modulus

Detect even/odd number with the modulus operator.

   <source lang="java">

public class Main {

 public static void main(String[] argv) {
   int x = 5;
   if (x % 2 == 0) {
     System.out.println("even");
   }
   if (x % 2 != 0) {
     System.out.println("odd");
   }
   // ... or binary AND operator...
   if ((x & 1) == 0) {
     System.out.println("even");
   }
   if ((x & 1) != 0) {
     System.out.println("odd");
   }
 }

Modulus Operator Example

   <source lang="java">

public class Main {

 public static void main(String[] args) {
   int i = 5;
   double d = 2;
   System.out.println("i mod 10 = " + i % 10);
   System.out.println("d mod 10 = " + d % 10);
 }

} /* i mod 10 = 5 d mod 10 = 2.0
